patented June 16, 1931 UNITED STATES HARRY M. ROSS, or INDIANAPOLIS, INDIANA, ASSIGNOR or ONE-HALF TO BEVERIDGE PAPER COMPANY, or INDIANAPOLIS, INDIANA, A CORPORATION PROCESS OF DECORATING PAPER Application filed August 3, I928; Serial No. 297,234.

This invention relates to a processand apparatus for decorating paper, and particularly that type of paper employed for use in calendars and binding work or the like.

The principal object of this invention is to produce an economical and practical method for use in production of paper of this character, wherein the elevations and depressions formed within the embossed paper may be colored in two or more colors or shades in such manner as to cause them to blend into each other. This is accomplished by embossing a paper having a natural or base color, applying a coloring material such as paint or the like to the projecting portions of the embossing roll so that such coloring material will be applied to the paper in the depressed portions only, and thereafter passing the paper between a pair of rolls having a film of coloring material thereon for causing the second coloring to be fully ap lied to the elevations of the embossed sur ace and partially applied to the intermediate portions of the embossed surface between the depressions and elevations so as to'create a blending or shading effect therebetween.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

Figure 1 is a diagrammatic illustration of the invention. Fig. 2 is a section taken on the line 22 thereof. Fig. 3 is an enlarged cross section through the decorated paper. Fig. 4: is a plan view'of the decorated surface of the paper.

In the drawings there is shown a roll of paper 10 having a natural or base color which is drawn therefrom under the guide roll 11 and over the counter roll 12 having an embossing roll 13 associated therewith for impressing the paper with configurations having a plurality of elevations and depressions. Associated with the embossing roll 13, which is provided with the embossing surface 1%, there is a plurality of color feeding rolls 15, 16 and 17. A quantity of coloring material 18 is carried between the rolls 16 and 17 so that the coloring material is applied to the surface of the roll 16 which transfers it to the surface of the roll 15, which, in turn, transfers the coloring material only to the elevations or projections of the embossing surface 14 of the roll 13. The coloring material carried thereon is applied to the paper so as to color the depressions formed therein by the embossing roll, leaving the elevations of the embossed paper free of such color. 1 The paper is then passed about the carrying roll 19 into contact with the coloring roll 20, about which it is carried to the guide roll 21. A quantity of paint 22 of a different color is supported between the embossed surface of the paper 10 and the surface of the coloringroll 20, and is thus brought into engagement with the embossed surface of the paper. I

As the paper is rapidly carried past the coloring material 22, such material adheres principally to the elevations of the paper, the depressions remaining substantially free therefrom by reason of thespeed of passage. Such paint as is carried on the surfaceof the coloring roll is likewise applied only to the elevations which are in contact therewith. Thus, a second color is directly applied to the elevations, while the first color 18 isapplied to the depressions. v The shading'eifect is obtained by varying the consistency of the coloring material 22, the relative speed of the paper and coloring "ATE'NT oFFicE roll, or the pressure exerted thereon between the rolls 19 and 20. Wherein the coloring material is of a thinner consistency, it will be caused to flow beyond the more pronounced elevations and approach the depressions, whereas with a coloring material of relatively stiff consistency there will be less tendency to flow into the depressions. A similar effect may be obtained by causing the paper to be compressed betweenthe rolls 19 and 20, which will temporarily flatten out the embossed surface causing the elevations and depressions to more nearly assume the same plane, by means of which the coloring material will be brought more into'contact with the depressions. As the coloring material is caused to spread or run from the elevations to the depressions, it will thin out I I and give the shading effect desired.

2 e me;

The invention claimed is:

1. The process of decorating paper, consisting in passing a sheet of paper under an embossing roll for forming elevations and depressions therein, applying a coloring material to the protruding surface of the embossing roll so as to cause such coloring material to color the depressions formed thereby in the paper, passing the paper about a coloring roll bringing a second coloring material into direct contact with the paper and cau ing the paper t be passed by the coloring material at such speed that said material will contact only with the elevations thereof and shade off into the depressions.

2. The process of decorating paper, consisting in passing a. sheet of paper under an embossing roll for forming elevations and depressions therein, applying a coloring material to the protruding surface of the embossing roll so as to cause such coloring material to color the depressions formed thereby in the paper, passing the paper about a coloring roll, and depositing a quantity of difierent coloring material upon said roll so as to be carried thereby into direct contact with the elevations on the embossed surface of the paper, whereby the embossed surface will be colored by said material, and

said material will shade ofl from the elevations to the depressions.

3. The process of decorating paper, consisting in passing a sheet of paper under an embossing roll for forming elevations and depressions therein, applying a coloring material to the protruding surface of the embossing roll so as to cause such coloring material to color the depressions formed thereby in the paper, passing said paper between a pair of rolls, and applying a quantity of different coloring material to one of said rolls so as to be brought into direct contact with the elevations formed on the paper, whereby the elevations of the surface will be 5 directly colored, which coloring will blend into the depressions by the flow of the material therein.

In Witness whereof, I have hereunto affixed my signature.

HARRY M. ROSS.
